VTo all whom t may concern:

Be it known that I, GZA JALsovIozKY, a subject of the Emperor of Austria-Hungary, residing at Buda Pesth, Austria Hungary,

5 have invented certain new and useful Improvements in Valve-Gear for Steam-Engines, of which the following is a specification.

The invention has been patented inAustria- Hungary January 16, 1891, No. 3,782; in Belro gium April 22, 1891, No. 71,259; in Germany August 13, 1891, No. 56,749; in England April 9, 1891, No. 6,097; in France April 23, 1891, No.199,814, and in Switzerland August 14, 1891, No. 334.

My invention is designed to provide a simple and eective form of governor valve and controlling mechanism, in which the resistance and friction is reduced to a minimum, and the working of the parts rendered easy zo and certain.

Referring to the drawings:-Figure I shows a View of the valve box of a steam engine with attached parts. Fig. II is asectional view on the line x-x of F i0. I, showing the cylindrical valve hereinafter described with connections for working the same. Figs. III, IV,

V and VI are views showing the manner in which the distribution of the steam is regulated by the governor through the movement 3o of the cylindrical valve. Fig. VII shows the attachment of the lever d2, hereinafter referred to, to its axle. Fig. VIII is a horizontal section on line :2c-x of Fig. II. Fig. IX is a horizontal section on line y-y of Fig. II,

A showing the4 manner in which the distribution of the steam takes place.

Similar letters and Iigures of reference indicate similar parts throughout the specification.

The slide valve of the steam chest is indicated at t. 0n the valve box, the cast iron cylindrical casing c is placed. The box and the casing are connected by the passage c.

A metal shell b is inserted in the casing c.

In this shell the cylindrical valve a moves.

This valve is provided inv this casing with four rectangular three cornered openings c', Figs.

III to VI, to which an equal number of openings b in the cylinder b correspond.

The cylindrical valve a is fixed on the rod f, which is placed in the holder e in such a way that it can move longitudinally therein, and also have rotary movement with the holder, for which purpose it has a'splined connection therewith. Thus the valve a can be revolved by the holder c and also be moved up and down. `loy the governor. For this latter purpose the rod fis connected with the governor device Y by means of the pin j and the fork d, Fig. II. Thefork is fastened on the axis d journaled in the casing which also carries the arm d2, Figs. VII and VIII on the outside of the casing. When this arm cl2, through the rod g, is actuated by the' movement of the governor lever Z, the fork,y d and with it the rod f and the cylindrical valve a. also receiveacorresponding movement. The fork lever d is secured on the axle d by a clamp device c. The exact adjustment of the cylindrical valve a may be effected by loosening the screw w and setting the forked lever d at the proper angle.

The supply of steam is controlled by the revolution of the cylindrical valve, steam being admitted to the chamber of the valve through the cylinder c attached to the steam pipe, and the passage c', as soon as the openings a of the cylindrical valve a fit over the openings b of the inserted shell b. In the example shown in the drawings,there are four openings a and b respectively. At each revolution of the cylindrical valve the steam will be 'admitted four times, which corresponds to two double strokes of the piston. Accordingly the engine must make two revolutions during one revolution of the cylindrical valve a. In order that this may be effected accurately, the rod t', serving to actuate the valve t as shown in Fig. Iis provided with the vertical rod m which transmits, by means of the rod n, its movement to the crank disk la- See Fig. II. The valve t, as just stated is moved by a reciprocating rod t', and this rod in turn is moved back and forth through any suitable connection witha 95 moving part of the engine or anywell known form of valve gear. The revolution of the crank is transmitted by means of the bevel wheels 10, 11, 12, and the shaft K in the cast iron case to to the governor and to the holder e. roo

To overcome the dead points of the crank, the crankaxle is further preferably revolved by means of a belt pulley s, in order t6 prevent any disturbances during its working by means of the rods m, n. The pulley s, is driven from any suitable pulley on the engine so that the movement of said pulley will bear a fixed relation to the reciprocation of the rod t the purpose being to operate in perfect unison with the operation of the rod t its sliding valve and crank 7c, and to carry the crank pin easily past the dead center. This uniformity of movement is insured by driving both the rod t and the pulley by means of connections with moving parts of the engine. i

The manner of driving the governor does not affect the essence of the invention, as it can also be operated in any other suitable manner, for instance by means of a chain and chain disks.

The diagrams shown in Figs. III to VI of the two cylinders a and b with the openings a and b exhibit the manner in which the governor regulates the inlet of steam through the movement of the cylindrical valve a. Three positions of the same are taken being somewhat higher and lower and which are distinguished respectively by l, 2 and 3. In 4each position views are given in Figs. III to VI, which correspond to the movement of the valve a. In position l of the valve, the apexes of the triangular openings come over one auother and a shutting off is effected if the valve has been moved longitudinally, as is shown in position l, Fig. V, where its course is designated by c. In position 2, this shutting off is effected only by alonger movement z2, and in position 3, the amount of movement z3 is still longer.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I claim l. In combination the governor, rotary sliding valve, the casing therefor, the valvetand its chamber arranged adjacent to the casing of the rotary valve and communicating therewith, the said rotary valve having longitudinal movement in its casing, the lever d within the said casing, connected With the valve stem, the outside arm d2 and the connection thereto from the governor, substantially as described. A

2. In combination, the valve casing, the rotary valve therein arranged to have sliding movement, the slide valve t, the governor having connection with the rotary valve for raising and lowering the Same, the means for rotating both the governor and the rotary valve consisting of the shaft extending through the casing u the gear 10 thereon, the gears ll and l2 connected respectively to the governor and the rotary valve andthe means for rotating the shaft consisting of themcrank disk and the connections m, n, therefrom to the slide valve t, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
